Kantronics KPC–3 Plus User Manual page 32

The computer-end of your RS232 cable must be female, to connect to the
computer's male serial (COM) port.
Hint: Since, the KPC-3 Plus' ―Computer‖ port has a female DSUB-25 connector, the
KPC-3 Plus end of your modem cable must have a male DSUB-25 connector.
Be sure the cable between your KPC-3 Plus and the computer is correctly wired. This
topic is covered when we get to the actual installation of the cable.
Technical note: To use your KPC-3 Plus with a non-PC compatible, use a serial
communication program and a serial modem cable (i.e., RS232 cable). You can get
help from your computer dealer, users group and members of the amateur radio
community. When talking with computer dealers or others who may not be familiar
with packet radio, refer to your KPC-3 Plus as an "external modem," not as a
"TNC," a less familiar term.
GPS Device (Optional)
The KPC-3 Plus works with Global Positioning System (GPS) devices that (1) support
the NMEA 0183 standard and (2) have a dataport through which they communicate.
The GPS device connects to the KPC-3 Plus through its serial (―computer‖) port, or
alternately, through a pin on its ―Radio‖ port.
Note: The GPS data port must be RS232 compatible to mate with the KPC-3 Plus.
